While the Yankees wait for young arms like Luis Severino and Ian Clarkin to get ready to make an impact in the Bronx, they added another right-hander to their system Wednesday, signing first-round pick James Kaprielian out of UCLA.

Kaprielian, a Scott Boras client, was the 16th pick overall and received a $2.65 million signing bonus, slightly above his slot figure of $2,543,300.

High school outfielder Trent Clark, taken by the Brewers with the 15th pick, signed for $2.7 million. Lefty pitcher Brady Aiken signed for $2.513 million after being selected at No. 17 by the Indians.

The deadline to sign was Friday. If the two sides didn’t get a deal done by then, Kaprielian could have gone back to UCLA for his senior year or gone the Independent League route.

Instead, the 6-foot-4, 200-pounder will join the organization after going 10-4 with a 2.03 ERA over 106 2/3 innings in 17 games during his final college season. He led the Pac-12 Conference in strikeouts for a second straight year.

The last time the Yankees were unable to sign their first-round pick was 2008, when Gerrit Cole opted to go to UCLA after the Yankees picked him 28th overall. He ended up being the first overall pick in 2011 by the Pirates and is now among the game’s best pitchers in the game.
